x = -1/2

4x² + 4x + 1 = 0

⇔ (2x + 1)² = 0

⇒ 2x + 1 = 0

⇔ x = -1/2

The value of x is 7.

Step-by-step explanation:

First, you have to make both fractions into 1 fraction :

$\frac{x}{3} + \frac{x}{6} = \frac{7}{2}$

$\frac{x \times 2}{3 \times 2} + \frac{x}{6} = \frac{7}{2}$

$\frac{2x}{6} + \frac{x}{6} = \frac{7}{2}$

$\frac{3x}{6} = \frac{7}{2}$

Next, you have to do cross-multiplication and solve the value of x :

$\frac{3x}{6} = \frac{7}{2}$

3x(2) = 7(6)

6x = 42

$x = 42 \div 6$

x = 7
